I don't think so. Once it is deleted it is gone forever. The Mecabricks Recycle Bin works similar to the ones on computers.

When a file is put in the bin and the bin emptied, it is gone for good.
If it is only in the bin, you can move it back to your library.

Oh. That's a pitty. Okay, thanks for answering.

Hey so, Im about ten days into using mecabricks. I was trying to get three models out of a folder, but I didn't know how, so me being me, deleted the folder, and its currently sitting in my bin. I dont know how to get it out of the bin, along with getting them out of the folder.

@Kazuhira_A7x If you didn't emptied your bin, you could choose that folder/file cut and then paste it into library (the switch button for bin/library is the gray one in the top right corner). And please don't press "empty" button!
